HIS Radeon HD 7770 GHz edition review -
Product Showcase

Connectivity wise the output connectors will vary per brand. HIS equips the card with two display port connectors (mini), HDMI and a Dual link DVI connector.

The HIS R7770 has a power consumption of give or take 80 Watts. The boards overall power consumption from idle to load is excellent really. Expect an idle wattage of roughly 10 Watt and when the monitor goes into power save mode, the card throttles down even lower towards 3 watt.

Here we can also see the cooler a bit better. Heatpipe based with a fans blowing over the aluminum heat sink. The cooler is performing nicely and the overall noise levels are non existent.

You will need to hook the 7770 up to your power supply with a 6-pin PCIe PEG connector. We recommend a 500 power supply to start with, with one card of course. You could opt to go with two cards in crossfire mode as there is one Crossfire connector available on the card.
